I always appeal tickets & will always go to the adjudicator if necessary. I've had my appeals upheld in the last half dozen or so cases where PCN's have been issued to us, including one when our Fiesta was removed to the pound. I received a full refund of the £200 it cost us to reclaim our car & l received a great sense of satisfaction in not caving in to the underhanded powers that be, as l always do.
